Billion Battles: The Multiverse of Fantasy

From BoardGameGeek:

Billion Battles is a fast-paced RPG that combines sneaky humour, creativity, and a touch of strategy. In this game, each player blindly selects a unique Hero and Power card, then a shared Goal is unveiled. Your mission? In 10 minutes, role-play your hero and engage in epic polemic battles trying to convince and outwit your fellow players as you make the most persuasive or funny statement on how you would achieve the shared Goal. However, here's the twist that adds a layer of amusement to the game - each player is assigned a hilarious hidden phrase that they must wive into their speech without anyone else noticing. The challenge lies in seamlessly blending this phrase into your role-playing narrative while keeping a straight face. The stakes are high, if someone catches you pronouncing your hidden phrase, you're instantly busted and out of the game. Billion Battles offers a unique and entertaining twist on role-playing games. Also, it includes various game modes, ensuring endless hours of laughter and fun for student parties or family game nights. -description from the publisher
